I have used a MQTT broker from the MQTT package on a RUT 955 with the mass production firmware [RUT9_R_00.07.04.5] which works fine, when upgrading to the latest firmware I am having trouble connecting to the broker, the warning message is that I am not authorized to connect but the broker does not use any TLS encryption or password/username, do you have any idea what this can be about?
Also, after enabling anonymous access, navigate to System → Administration → Access Control → Security and make sure that there are no IP blocks on the MQTT port (1883).
